摘　　要：近年来河西地区糯玉米种植面积逐年扩大,生产上对糯玉米新优品种的需求旺盛。为给甘肃省糯玉米品种更新换代、提高糯玉米的种植效益提供品种支持。以自交系JGF-1为母本、自交系14N08为父本配制杂交组合,经多年杂交选育出了鲜食糯玉米一代杂交种酒糯4109。酒糯4109在2020—2021年的甘肃省鲜食糯玉米区域试验中,2 a 10点(次)鲜穗平均折合产量为21756.9 kg/hm^(2),平均较对照品种增产24.8%。其中2020年酒糯4109鲜穗平均折合产量为22458.3 kg/hm^(2),比对照品种白玉糯909增产29.2%;2021年酒糯4109鲜穗平均折合产量为21055.5 kg/hm^(2),比对照品种京科糯569增产20.5%。该品种出苗至鲜穗采收107 d,株型半紧凑,株高285 cm,穗位高150 cm。果穗锥型,长24.4 cm,穗行数16行,行粒数40粒。粒色白间紫,糯质型,品质达糯玉米二级标准。籽粒淀粉含量中支链淀粉占比100%、粗淀粉(干基)含量70.46%。高感丝黑穗病和瘤黑粉病,适宜在甘肃河西地区种植。In recent years,the planting area of waxy corn in the Hexi region has been expanding gradually,and there is a strong demand for new and high-quality varieties of waxy corns in production.To Provide variety support for updating and improving the planting efficiency of waxy corn varieties in Gansu Province,Jiunuo 4109,a new fresh waxy corn F1 hybrid was bred and selected by using an inbred line JGF-1 as the female parent and an inbred line 14N08 as the male parent.Jiunuo 4109 participated in the regional experiment of fresh waxy corn in Gansu Province from 2020 to 2021and the average fresh ear yield from 10 locations in 2a was 21756.9 kg/ha,which was increased by 24.8%compared to the control.In 2020 the average fresh ear yield of Jiunuo 4109 was 22458.3 kg/ha,which was increased by 29.2%compared to the control Baiyunuo 909.In 2021,the average fresh ear yield was 21055.5 kg/ha,which was increased by 20.5%compared to the control Jingkenuo 569.Its growth period is about 107 days from emergence to fresh ear harvesting,its plant type is semi-compact,and the average plant height is 285 cm with an average ear height of 150 cm.The ear is cone shaped with an average ear length of 24.4 cm,the ear row number is 16,and the row number is 40.The grain is white and purple with a waxy texture which meets the second level standard for waxy corn quality,the amylopectin starch content accounts for 100%of the starch content in the grain,the content of crude starch(dry base)reaches 70.46%.It is highly susceptible to head smut and tumor smut.Jiunuo 4109 is suitable to plant in Hexi Corridor Region of Gansu Province.
